I saw your Regex function thread and the only limitation is that I have email fields scattered around the application so I'd have to create script files for each one because the field IDs are different. Multiple files doing the same thing is total anathema to me. But maybe SW's can work. I'm assuming as that thread is two years old, service workers are fully compatible across all browsers and devices now?Custom functions?Hi, I'm new to Quickbase but my background is database programming, mostly in SQL. Does Quickbase allow for custom/user functions? i.e. something I can pass variables into and receive an object/string/number back from?
